??? What are you talking about? Did you even look at the drawing of how the cables run? The cables DO NOT go inside the fork steerer tube. The cables go into the stem, then beside the fork steerer tube, then down into the headtube in that big wide headtube below the stem. The cables do not go through the steerer tube. The cables go AROUND the steerer tube. So how do you think water will get into the steerer tube? Are you going to drill a hole in the top cap or take out the center bolt?

If I look at the picture of the ICS stem and the fork of the TM01 or RM01 the disc brake cable is, you can see a cable entering the fork steerer, that seems to be the disc brake cable. So after the disc brake cable is going around the steerer tube it is then going inside the fork steerer and then in the fork itself, right? So water gould eventually get there in the fork steerer and into the fork. We speak here about the disc version.
And the other cables (disc brake rear and Di2) are going into the head tube and then in the down tube and then to the chainstay.
So theoretically water could enter below the stem where the cables are and then go to via the fork steerer to the fork and also to the down tube at least (maybe also a little bit to the top tube with the vibration as the cables are in the head tube with the opening of the top tube.
Is this thinking correct?
